OpenAI has rolled out GPT-5, its most advanced AI model yet, now available to 700m ChatGPT users. CEO Sam Altman says it delivers “PhD-level” expertise in coding, writing, health, and finance, with a standout feature that can instantly build software from text prompts, according to BBC.

The launch comes as tech giants pour billions into AI infrastructure. Early reviewers say GPT-5 handles coding and complex problems well, though the jump from GPT-4 is smaller than past upgrades. It can’t learn on its own but uses extra computing power to think through tougher questions, aiming to make AI more capable and widely accessible.
